The Macedonians, pressed by the Emperor's Violence toward them, send a Deputation to Liberius Bishop of Rome, and subscribe the Nicene Creed
When the maintainers of the 'homoousian' doctrine had been thus severely dealt with, and put to flight, the persecutors began afresh to harass the Macedonians; who impelled by fear rather than violence, send deputations to one another from city to city, declaring the necessity of appealing to the emperor's brother, and also to Liberius bishop of Rome: and that it was far better for them to embrace their faith, than to communicate with the party of Eudoxius. They sent for this purpose Eustathius bishop of Sebastia, who had been several times deposed, Silvanus of Tarsus in Cilicia, and Theophilus of Castabala in the same province; charging them to dissent in nothing from Liberius concerning the faith, but to enter into communion with the Roman church, and confirm the doctrine of the homoousian. These persons therefore proceeded to Old Rome, carrying with them the letters of those who had separated themselves from Acacius at Seleucia. To the emperor they could not have access, he being occupied in the Gauls with a war against the Sarmatæ; but they presented their letters to Liberius. He at first refused to admit them; saying they were of the Arian faction, and could not possibly be received into communion by the church, inasmuch as they had rejected the Nicene Creed. To this they replied that by change of sentiment they had acknowledged the truth, having long since renounced the Anomœan Creed, and avowed the Son to be in every way 'like the Father?': moreover that they considered the terms 'like' (homoios) and homoousios to have precisely the same import. When they had made this statement, Liberius demanded of them a written confession of their faith; and they accordingly presented him a document in which the substance of the Nicene Creed was inserted. I have not introduced here, because of their length, the letters from Smyrna, Asia, and from Pisidia, Isauria, Pamphylia, and Lycia, in all which places they had held Synods. The written profession which the deputies sent with Eustathius, delivered to Liberius, is as follows:
'To our Lord, Brother, and fellow-Minister Liberius: Eustathius, Theophilus, and Silvanus, salutations in the Lord.
'On account of the insane opinion of heretics, who cease not to introduce occasions of offense into the catholic churches, we being desirous of checking their career, come forward to express our approbation of the doctrines recognized the Synod of orthodox bishops which has been convened at Lampsacus, Smyrna, and various other places: from which Synod we being constituted a deputation, bring a letter to your benignity and to all the Italian and Western bishops, by which we declare that we hold and maintain the catholic faith which was established in the holy council at Nicæa under the reign of Constantine of blessed memory, by three hundred and eighteen bishops, and has hitherto continued entire and unshaken; in which creed the term homoousios is holily and devoutly employed in opposition to the pernicious doctrine of Arius. We therefore, together with the aforesaid persons whom we represent, profess under our own hand, that we have held, do hold, and will maintain the same faith even unto the end. We condemn Arius, and his impious doctrine, with his disciples, and those who agree with his sentiments; as also the same heresy of Sabellius, the Patripassians, the Marcionites, the Photinians, the Marcellians, that of Paul of Samosata, and those who countenance such tenets; in short all the heresies which are opposed to the aforesaid sacred creed, which was piously and in a catholic spirit set forth by the holy fathers at Nicæa. But we especially anathematize that form of the creed which was recited at the Synod of Ariminum, as altogether contrary to the before-mentioned creed of the holy Synod of Nicæa, to which the bishops at Constantinople affixed their signatures, being deceived by artifice and perjury, by reason of its having been brought from Nice, a town of Thrace. Our own creed, and that of those whose delegates we are, is this:
'We believe in one God the Father Almighty, the Maker of all things visible and invisible: and in one only-begotten God, the Lord Jesus Christ, the Son of God; begotten of the Father; that is of the substance of the Father; God of God, Light of Light, very God of very God; begotten not made, of the same substance with the Father, through whom all things were made which are in heaven, and which are upon the earth: who for us men, and for our salvation, descended, became incarnate, and was made man; suffered, and rose again the third day; ascended into the heavens, and will come to judge the living and the dead. [We believe] also in the Holy Spirit. But the Catholic and Apostolic Church of God anathematizes those who assert that 'there was a time when he was not,' and 'that he was not before he was begotten,' and that 'he was made of things which are not'; or those that say 'the Son of God is of another hypostasis' or 'substance than the Father,' or that 'he is mutable, or susceptible of change.'
'“I, Eustathius, bishop of the city of Sebastia, with Theophilus and Silvanus, delegates of the Synod of Lampsacus, Smyrna, and other places, have voluntarily subscribed this confession of faith with our own hands. And if, after the publication of this creed, any one shall presume to calumniate either us, or those who sent us, let him come with the letters of your holiness before such orthodox bishops as your sanctity shall approve of, and bring the matter to an issue with us before them; and if any charge shall be substantiated, let the guilty be punished.”'
Liberius having securely pledged the delegates by this document, received them into communion, and afterwards dismissed them with this letter:
The Letter of Liberius Bishop of Rome, to the Bishops of the Macedonians.
To our beloved brethren and fellow-ministers, Evethius, Cyril, Hyperechius, Uranius, Heron, Elpidius, Maximus, Eusebius, Eucarpius, Heortasius, Neon, Eumathius, Faustinus, Proclinus, Pasinicus, Arsenius, Severus, Didymion, Brittanius, Callicrates, Dalmatius, Ædesius, Eustochius, Ambrose, Gelonius, Pardalius, Macedonius, Paul, Marcellus, Heraclius, Alexander, Adolius, Marcian, Sthenelus, John, Macer, Charisius, Silvanus, Photinus, Anthony, Aythus, Celsus, Euphranon, Milesius, Patricius, Severian, Eusebius, Eumolpius, Athanasius, Diophantus, Menodorus, Diocles, Chrysampelus, Neon, Eugenius, Eustathius, Callicrates, Arsenius, Eugenius, Martyrius, Hieracius, Leontius, Philagrius, Lucius, and to all the orthodox bishops in the East, Liberius bishop of Italy, and the bishops throughout the West, salutations always in the Lord.
